CVE-2026-43906 is fixed in 6 products on 1 platform, first by libopenimageio2.1 2.1.12.0~dfsg0-1ubuntu0.1~esm1, released May 14, 2026. It is not reported as exploited. Patch Radar priority: High.
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a heap-based buffer overflow in the HEIF decoder of OpenImageIO allows out-of-bounds writes via crafted images due to a subimage metadata mismatch, leading to memory corruption and potential code execution. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
